Lifecourse factors associated with flourishing among US children aged 1-5 years.

Findings indicate that several lifecourse factors are associated with young children's flourishing, including being female, White, non-Hispanic, not having a special health care need or EBD, English as a primary language, parents receiving emotional social support, having neighbourhood support and a lower household income. Our findings promote the continuation of programmes supporting diverse and low-income children's families and communities such as home visiting and Head Start, which provide avenues for bolstering children's health and development across the lifespan.
